Connection to Postgresql hosted on AWS RDS using assume role and IAM

[arthurzenika]

Looking at https://go.dev/wiki/SQLDrivers I don't see a reference to iam/passwordless based connexion to Postgresql hosted on RDS. Is this possible with sql_exporter ?

A quick search leads me to other projets such as https://github.com/labd/go-rds-iam and https://github.com/krotscheck/go-rds-driver ... do you think they would be "compatible" with sql_exporter ? (sorry not a golang developer)

Hey @arthurzenika, unfortunately I don't have any experience with that. It seems that it would be possible to implement it based on other discussions I found (https://github.com/califlower/golang-aws-rds-iam-postgres/issues/5), so it seems that it would definitely need some code changes.

For now I'd say it's not supported. If someone wants to take this up and implement it we would support it.

Hi @dewey, hope you are well.

Here is a first attempt to contributing some rds+postgres+iam specific code. I am not a golang dev so I hope I didn't do anything wrong, feel free to correct or as me for corrections. (especially the vendor stuff which I am not used to)
